WRENCH.

SPECIFICATION forming part of Letters Patent No. 699,234, dated May 6, 1902. Application Iiled September 13, 1901. Serial No. 75,347. (No model.)

To a/ZZ whom it may concern: l y

Be itknown that LWILLIAM JOSEPH QUINN, a citizen of the UnitedStates, residing at Saranac, in the coun ty of Clinton and State of New j York,have invented a newand useful Wrench, of which the following is a specification.

My invention is an improved wrench which is adapted for use both as a nut-wrench and as a pipe-wrench; and it consists in the peculiar construction and combination of devices hereinafter described and claimed.

One object of my invention is to provide a wrench which may be readily adjusted for operation on nuts, pipes, or other objects of varying size.

A further object of my invention is to provide a wrench with an operating-lever which aords leverage and also serves to keep the jaws in operative engagement with the nut or pipe.

A further object of my invention is to provide a wrench composed of elements which may be readily assembled'or disassembled and which are connected together when assembled by a single removable bolt, screw, or pin.

A further object of my invention is to provide a wrench with an operating-lever which is geared to the sliding jaw and serves to operate the sliding jaw and to also afford leverage for turning a nut or pipe with which the wrench is engaged.

A further object of my invention is to provide means for readily disengaging the saidi operating-lever from the sliding jaw and for adjusting the gearing between the said lever and the jaw to compensate for Wear.

In the accompanying drawings, Figure lis a side elevation of a wrench embodying my improvement. Fig. 2 is a transverse section of the same, taken on a plane indicated by the line a a of Figyl'. Fig. 3 is a detail view, partly in elevation and partly a longitudinal section, of the same.

The fixed jaw 1 of my improved wrench is provided with an ar1n'2, which projects from its inner side.j The. said arm has 'at a suitble distance from its inner end a circular transverse opening 3, which is of suitable diameter. A longitudinal bore 4 in the said arm 2 communicates at one end with one side of the said opening 3.

The sliding jaw 5 has a guide or arm 6, into which the arm 2 projects, the said guide, together with the said jaw 5, being adapted to slide backward and forward on the said arm 2 to adjust said sliding jaw with relation to the Xed jaw. The upper portion 7 of the said guide 6 corresponds in Width with the thickness of arm 2. The lower portion of the said guide is wider, the said lower portion of 6o said guide projecting laterally beyond the opposite sides of the said arm 2, and on each of the said projecting portions of the lower side of the said guide is formed a rack 8, having serrated teeth 9. The shoulders 10 are formed 65 at the outerend of the said racks on opposite sides of the said guide. h

An eccentric 11 is fitted inthe opening 3 of the arm 2 andis adapted to partly rotate therein. The said eccentric has a notch or 7c recess Vv12 in one side of its periphery, which notch or recess is adapted to be engaged by a spring-pressed bolt 13,Y whichis disposed in the bore 4. The operating-lever 14C has its inner end forked or bifurcated to form the which` are serrated and adapted to engage Se those of the racks 8. AA bolt, screw, or pin 17 is .passed through openings in the arms 15, which openings 'are' centrally, disposed with reference'tothe gear-segments `16, and the said'bolt', screw, or pin is passed through an 8 5 opening which` is' disposed eccentrically in the eccentric 1l. The said bolt, screw, or pin serves to pivotY the Yop'er'ating-lever 14 to the arms 2, so that when the gear-segments 16 are in engagement with the racks 8 the sliding 9o jaw 5 may be by means of the said lever 14 moved toward or from the fixed jaw 1 to enable the said jaws to engage a nut, pipe, or other object to be turned by the wrench. It

will be understood that the lever 12h-.which is 95 thus geared to the slid ingljaw, serves not only to operate the said sliding jaw, but also to aord leveragel by which thewrench may be operated'to turn or holdthe nut, pipe, or

other objects on which it is employed. By loc turning the eccentric through a partial rotation in theopening 3 the pivot 17, and hence the lever 14:, may be moved sulciently to disengage the gear-segments 16 from the racks 8 in order that the sliding jaw 5 may be adjusted as may be required to adapt the wrench to be used in connection with nuts or other objects of varying sizes. When the said segments 16 are in engagement with said racks 8, the spring-pressed bolt 13, which engages the eccentric, prevents the latter from being turned in ordinary usage, and hence the said operating-lever 14 is kept geared to the sliding jaw 5; but by jerking upwardly in the direction of its length on the said operatinglever 14, or by hammering the head of the fixed jaw 1 on an object, or by striking the lever 14 against the shoulders 10 the eccentric 11 maybe started,notwithstandingthe springpressed locking-bolt, and turned to the extent required to disengage the lever gear-segments from the racks of the sliding jaw, as Will be understood.

It will be understood that as the gear-segment 16 and the racks 8 wear the eccentric 11 will t-urn in the opening 3 to compensate for the wear of the said parts, and hence the lever 14 will be kept geared to and in operative relation with the sliding jaw.

The inner sides of the jaws 1 5 are fretted or serrated to enable the same to readily grasp a round object, such as a pipe, when the wrench is used as a pipe-wrench.

It will be understood that by turning,r the operating-lever 14 in the position shown in Fig. 1 the wrench can be used in a space equal to only halt the normal length of the wrench, which is a matter of great importance where the work must be performed in a contracted space.

Having thus described my invention, what I claim is- 1. In a wrench, the combination of a fixed jaw having an arm, a sliding jaw on said arm, and a lever pivotally supported by said arm and geared to said sliding jaw to operate the latter, the said lever also serving as the handle for operating the wrench, substantially as described.

2. In a wrench, the combination of a fixed jaw having an arm, a sliding jaw guided on said arm and having a rack, and an operating-lever pivoted to said arm and having a gear engaging said rack, to operate said sliding jaw, said operating-lever also serving as the handle for operating the Wrench, substantially as described.

3. In a wrench, the combination of'a fixed jaw having an arm, a sliding jaw having a rack, an operating-lever pivotally connected to said arm and having a gear engaging said rack, and means to shift said gear out of engagement with said rack to enable said sliding jaw to be adjusted, for the purpose set forth, substantially as'described.

4. In a wrench, the combination of a fixed jaw having an arm, a sliding jaw carried by said arm, an operating-lever pivoted to said arm, connections between said operating-lever and said sliding jaw, and means to disconnect said operating-lever from said sliding jaw, to enable the latter to be adj usted, independently of said lever, with relation to said nxed jaw, substantially as described.

5. In a wrench the combination of a fixed jaw having an arm, a sliding jaw carried by said arm, an operating-lever, pivoted to said arm and connected to said sliding jaw, to actuate the latter, and means to shift the pivot of said operating-lever and thereby disconnect the same from said sliding jaw, for the purpose set forth, substantially as described.
